摘要
The austenitic stainless steel SUS 304 with oxide scale was directly cold rolled at different reductions of 10%, 20% and 30% respectively. It was proved that the surface quality （lower surface roughness） of the cold rolled products was achieved after subsequent annealing and pickling possesses, compared to the conventional hot rolled No. 1 product, whereas the grain size, mechanical and corrosion-resistant properties were comparable to those of the No. 1 product.
